Hello,

I just found a review of the new ultra-wide angle Samsung NX lens (http://erphotoreview.com/wordpress/?p=3124) and was able to extract the lens ID from sample images (12).

I propose to update the lens database apropriately.

As my older patch is still not in trunk, I am not sure how to handle this one. Anyway, we are looking at adding a line like this to the database: { 12, N_("Samsung NX 12-24mm F4-5.6 ED") }
